SHEET-METAL' GHURN' TOP.

Application filed August 25, 1925. Serial No. 52,453.

To all whom may concern.

Beit known that I, OSCAR T. SMITH, a citizen of the United States, residing at lVellsburg, in the county of Brooke and State of Vest Virginia, have invented certain new and useful Improvements in Sheet- Mctal Churn Tops; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to churns, or more particularly to a sunken cover for milkcans having certain characteristics adapting it for use as a churn top, and for con veniently and quickly converting an ordinary milk shipping can into a churn.

The invention has for a further object the production of sheet metal churns including covers, which are extremely durable and entirely free from shrinkage or the absorption of odors, so frequently experienced with ordinary wooden churn barrels and tops.

With the foregoing and other objects in view the invention will be hereinafter particularly described and then set forth in the claims following.

In the accompanying drawings forming part of this application for Letters Patent, and whereon like characters indicate corresponding parts in the several views:

Figure 1 is a side elevation of an ordinary sheet-metal milk can upon a greatly reduced scale, broken away at its neck portion thus showing the improved churn-cover in operative position, the latter also being partly broken away centrally.

Figure 2 is a top plan view of churncover detached, and upon a relatively en larged scale.

Figure 3 is a central vertical transverse sectional view of cover taken on the line preferably of unitary construction, and

pressed into the sunken or cup-shaped form common to milk can covers, having an outwardly flaring top portion 6, conforming in shape to the neck of such shipping cans, and a convex bottom 7 asbcst shown by Figures 3 and 4c of the drawings.

The convex form of the said bottom 7 insures structural rigidity and has other functional advantages as will later appear, while at suitable points in the lower edge of said top, where its side walls and bottom join,

there are provided drip-holes 8, 8, for purposes that will also hereinafter appear.

Crossing the fianged and sunken churn top 2 transversely, from the bottom of its flaring sides 6, 6, is a semi-tubular handle 9, the ends of which extend through said sides being there clinched and spot-welded or otherwise permanently secured as shown.

Directly through the center of said han dle 9, and also through the center of the con-.

vex bottom 7 projects a tubular churndasher guide 10, having a smooth interior, and open at both ends as shown by Figure 3, being securely fastened, as by welding, at points where it passes up through bottom 7 and handle 9. Through this guide tube 10 passes the handle of a churn dasher 11, as shown by Figure 1, adapted to be reciprocated freely therein.

\Vhen it is desired to convert an ordinary shipping can into a churn, the usual closed cover (not shown) is removed, the handle 1]. of a churn dasher is passed upwardly through tubular guide 10, and, thus equipped, my improved churn-cover is substituted for the ordinary can cover.

The churning operation then proceeds as in the ordinary upstanding substantially cylindrical wooden churns, and it will be noted that handle 9 aifords a most con venient hold at times for the free hand of an operator, that the convex form of bottom 7 adds materially to rigidity of the structure and discourages slopping over, that a true vertically reciprocal action of the dasher handle is insured, and that any buttermilk or cream that may find its way through the tubular guide 10 is immediately conducted down the convex surface of bottom 7 to drip holes 8, 8, and thence directly back into the churn,

This being a description of my invention,

its use and operation, What I now claim and desire to secure by Letters Patent is:

1. A sunken sheet metal churn cover in combination with a tubular guide for a dasherhandle rising centrally from the bottom pfsaid cover and spacedlaterally from the surrounding tvalls thereof.

2. A sunken churn-coveriu combination with a transverse handle connecting opposite sides of said cover and a tubular guide for a dasher handle projecting through the bottom of said cover as'also through the transverse handle aforesaid.

5. A sheet metal churn cover of cup form tubular open ended guide for a dasher hen-- dle rigidly secured to said bottom and spaced laterally from the surrounding walls of the structure.

l. A sheet metal churn-cover of sunlmi cup. form in con'ibination with a handle crossing the structure diametrically, a con-- vex bottoin provided with return drip-openings and a tubular guide for a dasher-handle projecting centrally through the bottom of said cover and through the handle afore said.

Intestimony whereof I a-flix my signature OSCAR '1. SMITH.
